I should do a write-up but basically it was a combination of running tailscale (which sends a packet to an unroutable UDP destination nonstop [1]) and my game taking off at the same time. It triggered their false-positive-laden DDOS protection. I responded to the email straight away explaining it was fully under my control and not being attacked. I filled out their attestation form of the same, which is supposed to grant you 24 hrs before they block all traffic. I had responded within a couple hours.

They blackholed my server right when things were starting to hockey stick and took until the following day to unlock it. I lost a ton of users to a full outage while I had an unplanned migration to AWS.

When they finally unlocked my server their tech responded to my ticket begging them to unlock my server with an extremely condescending “It’s unlocked but I’m certain you’re not in control of this server”

Anyway, never again. I’ll pay a premium for stability and intelligent support staff and systems that don’t automatically blackhole your server.
